Palaearctic species of the genus Confluaria Ablasov (Cestoda, Hymenolepididae): redescriptions of C. podicipina (Szymanski, 1905) and C. furcifera (Krabbe, 1869), description of C. pseudofurcifera n. sp., a key and final comments

Abstract

Redescriptions are provided of Confluaria podicipina (Szymanski, 1905) (specimens from Podiceps nigricollis and Tachybaptus ruficollis from Bulgaria) and C. furcifera (Krabbe, 1869) (syntypes from P. grisegena from Denmark and specimens from P. grisegena, P. nigricollis and T. ruficollis from Bulgaria). C. pseudofurcifera n. sp. is described from P. cristatus from Switzerland and Bulgaria. The previous records of C. furcifera from P. cristatus in Switzerland (Joyeux & Baer, 1950), Poland (Jarecka, 1958; Korpaczewska, 1960), Czech Republic (Rysavy & Sitko, 1995) and Baltic Coast (Galkin, 1986) are recognised as belonging to C. pseudofurcifera. Confluaria Ablasov in Spasskaya, 1966 is recognised as a valid genus and Dimorphocanthus Maksimova, 1989 is confirmed as its synonym. A key to the Palaearctic species of Confluaria is presented.

Cestode communities in non-breeding populations of four grebe species (Aves: Podicipedidae) from the Bulgarian Black Sea Coast

“…Their narrow specificity is confirmed by data on their previous host records (Sulgostowska & Korpaczewska, 1969;Rees, 1973;Vasileva et al, 1998;1999c). In addition to them, there is an inter mediate group between the typical «stenoxene» and "oiioxene" parasites, which includes C. multistriata and M. podirufi.…”

Cucolepis cincta gen. n. et sp. n. (Cestoda: Cyclophyllidea) from the squirrel cuckoo Piaya cayana Lesson (Aves: Cuculiformes) from Paraguay

“…the phenomenon of postlarval growth of rostellar hooks is not frequent across the order cyclophyllidea and is to occur in members of the paruterinid genera Triaenorhina (see spasskii and shumilo 1965) and Cucolepis (present study) as well as for the hymenolepidid genus Confluaria ablasov in spasskaya, 1966 (e.g., Vasileva et al 2000) and for some gryporhynchids (e.g., scholz et al 2002). therefore, it should be regarded as an independently developed characteristic in several cestode families.…”

Parasites of the Southern silvery grebe Podiceps occipitalis (Aves, Podicipedidae) in Chile

“…Vasileva et al (1999a) indicate that the genus Confluaria is restricted to Podicipedidae, and that records in other avian families are erroneous. This genus has been reported in P. ruficollis japonicus, P. nigricollis, Tachybaptus ruficollis, P. grisegena, P. cristatus and P. auritus in Asia and Europe (VASILEVA et al, 1999a, b;BARUŠ et al, 2000;VASILEVA et al, 2000VASILEVA et al, , 2001VASILEVA et al, , 2008HAUKISALMI, 2015;SITKO & HENEBERG, 2015). In South America, the genus Confluaria is only known to be from Northern Brazil, with P. dominicus serving as its host (VASILEVA et al, 1999a).…”
